American Kestrels are the smallest falcons in North America. This tiny raptor has a wingspan of 22 inches and weighs 4.1 ounces. It eats small mammals, insects and today it ate a finch from our feeder. This bird is a male because of the blue on its wings. It was minus four this morning before the sun came out. Normally this bird has a sleek appearance but it fluffed its feathers in order to keep warm.
